Which do you choose first: mobo or cpu?

Motherboard or CPU first?

Just a curiosity question, when building a computer from scratch, what do ya'll choose to do first:
Pick a CPU and then a compatible motherboard?
Pick a motherboard and then a compatible CPU?
Or something different?

The motherboard is probably the most important component in the system. The motherboard must support all the features you want in a system at the time of purchase. An OEM Windows license is even bound to the motherboard during activation. However you must pick a motherboard based on all the components you want to use. And the CPU should be the first component you pick for a system.

It's agreed then, CPU first, because, for instance, if the CPU is unlocked, you'll want a higher-end board that supports stable overclocking, but if it has a locked multiplier, a much cheaper board/chipset can be used (and a smaller power supply, cheaper case with fewer fans, etc).
